Definitions

  • a chain of ethylene oxide is connected to a molecule of the color former by polymerizing either ethylene oxide or its homologs directly onto a preliminary product of the color former or by connecting the color former to a suitable intermediate product which carries a chain substituent consisting forinstance of polyethylene oxide.
  • the color former .obtained therefrom may be treated with alkali for a long timewithout difllculties or it may be sulfonated, since the acetals, contrary to the acetates, are not split up under the given conditions.
  • Example V 15 grams of the condensate obtained according to Example I from 40 grams of acetoacetyl amino phenyl carboxylic acid and 40 grams of the chloropropion acetal frompolyvinyl alcohol, treated with ammonia, are added to 1 kg. of silver halide emulsion. If worked up according to Example I, yellow dyestuff images are obtained.
  • Silver halide emulsions containing as a color I former fast to diffusion the condensation product of a compound capable of reacting with the oxidation products of a primary aromatic amino developer to produc a dyestuff image with apolymer containing secondary amino groups obtained by the amidation of a halogenated polyvinyl acetal, said polymer containing amino groups beingjoined to said compound by a linkage selected from the class consisting of carbonamide, sulfonamide, azomethine and direct nuclear carbon to nitrogen linkages.
